Question: The free service follows a roll out across 2,000 branches in the US.
Newsbeat's social media survey last October suggested one in four 15 to 18-year-olds felt happier online than in real life, but it's tricky to stay online if your phone dies when you're on the go.
So how will you be able to use wireless charging?
Wireless charging, as the name suggests, means you can charge up your phone without using a plug socket.
Of the two wireless charging standards currently available, Starbucks has chosen to use Powermat, requiring users to plug in an adapter to their phone.
This means customers will be supplied with a ring-shaped device which is set up with adapters for Apple devices and phones using the micro USB standard.
To charge efficiently, phones must be placed on specially-equipped tables that Starbuck is installing in the initial 10 branches across London.
Ian Cranna, vice president of marketing and category at Starbucks, said: "We have always tried to anticipate our customers' needs and innovate with technology to provide even more convenience.
"We're delighted to be the first to launch Powermat wireless charging in 10 London stores and look forward to customers being able to charge their phones wirelessly in many more stores soon."
If you live or work in London, the branches will be; Princes Street, Kingsway, Wardour Street, Pentonville Road, Harewood Place, Berkeley Street, Great Portland Street, Moorgate, Fleet Street, and Euston Tower.

Question: Murphy lost to Stuart Bingham in last year's final but gained revenge with a 10-9 Grand Prix win in Llandudno.
The 33-year-old was 2005 world champion and is keen to win snooker's biggest tournament, which starts in Sheffield next month.
"I got to within three frames of winning last year, let's see if I can go three better this year," he said.
"I think if I can prepare in the same way as I did last year and continue doing the right things that I think I'm doing with my coach and my team, then I arrive in Sheffield in great form and good nick," he said.
"It doesn't mean you're going to win - it doesn't mean you're going to win your first match. But I'll give myself the best possible chance."
Murphy won his sixth ranking event, and his first in two years, by beating Bingham in north Wales and he was delighted to bring what he described as a "slump" to an end.
"I had a fantastic year in 2015 - victory in the Masters, nearly winning the world title and nearly winning the German Masters as well but nothing quite beats taking trophies home," he said.
"That's what we play for. That's what it's all about. No-one comes for second place.
"It's very difficult winning ranking tournaments. With three events left of the season it really points to good things for me "

Answer:
World Grand Prix champion Shaun Murphy has set his sights on winning the World Championship for a second time.
